Question about 2001 Mercedes-Benz C-Class
I have just bought a 2003 C200 Kompressor, when I start the car from cold the tick over is a bit rough and if I put it in reverse or drive the engine hunts badly making it impossible to get out of a roadside parking space safely. After 30 to 40 seconds or so its fine and the engine runs smoothly. Mercedes garage says they cant find anything and there are no malfunctions showing in the computer system. Anyone have any ideas what could be wrong? It seems to be like a choke / mixture problem but only for a very short time. HELP.
Change the pcv valve.check the IAC valve and clean the throttle body with cleaner and make sure the butterfly is free moving.check all the vacuum hoses and all hoses are tight fitting,even the one on the air filter assembly.a small leak can throw off the air flow meter.
check all the plugs are tight.

My sister has one of these. It has a supercharger. When started, the computer system takes a bit to get the fuel injectors and other settings ironed out. It takes a few seconds longer than the larger (non-super charged) engine or Benz turbo to get right. A lot of gizmos on this car.
By the way, it's always a good idea to give any car a minute to get it's fluids flowing and sensors working the proper settings.
